FASTENER FORCOVEES 0}? WASHING MA CHINES.

Application filed February 11, 1918. Serial No. 216,461.-

Be it known that I, BERT A. STOCKING, a citizen of the United States, residing at Boone, in the county of Boone, and State of Iowa, have invented certain new and useful ,t onal v1 ew:-of a washing-machine embody Improvements in Fasteners for Covers of Washing Machines, ofwhich the following is a specification. o j

My invention, relates to washing machines, and more particularly to. improved means for securing the lid in locked position.

One of the'troublesome features in connection with washing machines hasheretofore been the loss of time, worry. and annoyance caused by the inconvenient arrangement and difficult manipulation of the various forms of locks used to secure the lid in closed position uponthe tub. 'All'thisis obviated by my new form of lock, to manipulate which all that is necessary is to. simply turn the conveniently arranged and readily accessible handle through ninety degrees, which when unlocking results in the locking parts being automatically thrown and held out of engagement, and when looking securely holds the parts, inlocked engagement.

Among the objects of nay-invention therefore is the provision of easily manipulated and conveniently arranged means for securely locking thelid of a washing machine.

in operative position upon the tub; further to provide such means in which by simple turning of the handle the locking parts will be automatically disengaged; further to so arrange the locking member carried by the lid that after being unlocked it will be positively held in unlocked position until the handle is again .turnedf'or locking; further to so construct'the handle ofvthe locking means that when turned into locking posi tion the locking parts are positively locked against disengagement; further to provide such form of lock that may be used tolo-ck together, any two parts in which one part is arranged for movement toward and away from the other; and further to provide such combination, construction and arrangement of parts as will result in a more simple, economical and etlicacious device of the class described.

Further objects and advantages will become apparent as the following description proceeds.

In the drawings, while I have illustrated a preferred embodiment of my invention, I desire it to be understood that the same is ready to be" assembled.

susceptible-of modification and change without departing fromthe spirit of my invention. I

Referring to the drawings: F 1g. 11 is a transevrse vvertical cross secing my invention. I 1

' F1g52'1s-a fragmentary plan view of a portion of the tub, showing my improved .fOIHLOf lock thereon Fig. 8 is a view showingthe'parts of my. improved lock in separated position H In the drawings, upon the tub l is mounted thelid 2, through which extends the shaft 3,; which imparts suitablemotioni to the .dasherj 4, The tub is surrounded; by the usual; hoops 5and 6. Securely locking the lid incposition on the tub is-rny improved form of lock designated generally by A, and

which look is made up as follows: Upon the lid 1 and near one edge thereof is securely mounted the plate 7, and upwardly extendingfrom this plate is. thepin 8, upon which is rotatably inountedfthe handle 9.

The portion of the handle immediately surrounding the pin 8 is ofjelon'gated formation, the two edge portions 9 of which vir. tually form earns, the purpose for which will later appear. Afsuitablev head 10 is providednupon the upper end of the pin 8 for the purpose ofholding the handle 9 in properposition. The plate 7 is provided with suitable apertures 11 and 12 for securing-the same in position uponflthelid 2, and at itsforward portion is also provided with cars 13 and 14:, which are'bent upwardly then inwardly to form the slot15 as clearly r shown in Fig. 3. Mountedwithin-this slot 15 for. longitudinal sliding movement is the latch plate 16, whichis. provided with the I downwardly extending portion; 17, upon which is formed the inwardly extending projection 18 which'lies in substantially parallel relation to the plate 16. The portion 17 has formed therein a suitable socket 19' for the reception of the end of the spring 20, which spring is inserted in the socket 21 formed in the lid 2 and is of such length as to be under compression when'the parts are I in looking position, and thus exerts an outward thrust on the portion 17 of the sliding latch. It is obvious, of course, that other equivalent means may be employed for holding the outer end of the spring 20 in engagement with the portion 17 of the latch if desired, for example, a projection instead of a socket.

Suitably formed in the upper portion of the latch 16 is a slot 22, which slot adapted to receive the pin 8 and to permit the latch 16 to have a longitudinally sliding movement on said pin. The plate 16 is further provided at its rear portion with the upwardly extending projection 23. Mounted upon the tub portion and adjacent theupper edge thereoi is the socketmember or angle piece 24:, in which is formed the offset portion 25 to fit over the hoop 6. Upon the upper end of the angle piece 24 is an outwardly extending projection 26 of a length substantially equal to that of the inwardly extending projection 18 of the latch 16. The members 24h and 7 are secured to the tub by means of screws, bolts, or other suitable tasten-ing devices.

The operation of my improved loclr is as follows: Assuming that the parts are in locked position as shown in Fig. 1 and it is desired to throw them into unlocked position, all that is necessary is to grasp the handle 9 and rotate the same through an angle of ninety degrees, which operation removes the engaged cam 9 away from engagement with the projection 23, thus permitting the latch plate to move forwardly upon the plate 7 under act-ion of the spring 20, which movement automatically disengages the projection 18 of the latch plate from the projection 26 of the socket memher or angle piece 24. As long as the handle 9 stands in unlocked position the projection 18 will stand out of engagement with the projection 26, as a result or the continual outward pressure exerted on the portion 17 by the coil spring 20, thus insuring that the.

locking parts will be completely disengaged until it is desired to again lock the lid on the tub. VJ hen it is desired to lock the lid in position on the tub, the handle 9 is 1'0- tated through an angle of ninety degrees, which eiliects the reverse operation of that just described. In other words, this rotation of the handle 9 brings the cam 9" into engagement with the projection 23, thus forcing the latch plate 16 backwardly upon the plate 7 until the projection 18 again engages the projection 26. This movement compresses the spring 20, which compression of the spring holds the projection 23 firmly against the cam 9, and thus insures the handle 9 from arrlng loose or being accidentally turned.

so held until lookin is a ain desired. This b b arrangement of parts gives the maximum of simplicity, and results in a lock which entirely obviates the bother, vcXation, and loss of time heretofore present in the more clumsy and complicated forms of locks. While my improved lock is especially adapted for use in locking the lid of a tub in washing machines, it is, of course, evident that the same may be used in locking together any two parts in which one part swings or similarly moves toward and away from the other.

Having now described my invention,

I claim I 1. In apparatus of the class described, two members to be locked together, a plate on one or said members, a pin on said plate, a latch having an elongated slot'iitting over said pin, ears on said plate bent to overlie said latch, a handle on said pin, a cam on said handle, a projection on said latch adapted to engage said cam, latchrreceiving means on the other of said members, and a spring norm-ally pressing said latch in one direction, whereby upon rotation of said sliding said latch and holding it in lockedv position, and further means for automatically disengaging and normally holding apartsaid latch and angle plate upon suitable manipulation of said single means.

In witness whereof, I hereunto subscribe my name to this specification.
